AI Technical Summary

Benefits of technology

The film system achieves efficient removal of contaminants, maintaining surface cleanliness and reducing visibility of fingerprints and oils, while being durable and resistant to scratches and microbial growth.

Problems solved by technology

Other devices, such as cameras and eyeglasses, generally include a lens surface which may be inadvertently touched by an operator during use.
Therefore, during use, an operator may deposit fingerprints and / or oils onto such devices and surfaces.

Embodiment Construction

[0021]Referring to the Figures, wherein like reference numerals refer to like elements, a self-cleaning film system 10 is shown generally in FIG. 1. The self-cleaning film system 10 is configured for reducing a visibility or conspicuity of a contaminant 100. For example, the self-cleaning film system 10 may be suitable for applications in which an operator may touch and deposit fingerprints, oils, and / or other organic or carbon-based contaminants 100 or pathogens onto a screen, lens, or surface. More specifically, the self-cleaning film system 10 may be useful for applications requiring a clean, substantially fingerprint-free screen, lens, or surface. That is, the self-cleaning film system 10 may be useful for removing fingerprints and other organic contaminants 100 from such screens, lenses, or surfaces.

[0022]For example, the self-cleaning film system 10 may be useful for automotive applications such as in-dash navigation systems which include a touchscreen, or vehicle cameras whic...

Abstract

A self-cleaning film system includes a substrate and a film. The film includes a monolayer formed from a fluorinated material, and a first plurality of regions disposed within the monolayer and spaced apart from one another such that each of the regions abuts, is surrounded by, and is not covered by the fluorinated material. Each of the regions includes a photocatalytic material. The system also includes a wave guide disposed adjacent the substrate. The wave guide includes a first light source configured for emitting a first portion of electromagnetic radiation towards the film having an ultraviolet wavelength of from 10 nm to 400 nm, and a second light source configured for emitting a second portion of electromagnetic radiation towards the film having an infrared wavelength of from 700 nm to 1 mm. A method of forming a self-cleaning film system configured for reducing a visibility of a contaminant is disclosed.

Description

INTRODUCTION[0001]The disclosure relates to a self-cleaning film system and to a method of forming the self-cleaning film system.[0002]Devices, such as display systems, are often designed to be touched by an operator. For example, a vehicle may include a display system that presents information to an operator via a touchscreen. Similarly, an automated teller machine or kiosk may include a display system that is activated by touch.[0003]Other devices, such as cameras and eyeglasses, generally include a lens surface which may be inadvertently touched by an operator during use. Further, other devices such as vehicles, windows, mirrors, appliances, cabinetry, furniture, cellular telephones, fingerprint scanners, sensors, copiers, medical instruments, and countertops may also include one or more surfaces which may be touched by an operator. Therefore, during use, an operator may deposit fingerprints and / or oils onto such devices and surfaces.SUMMARY[0004]A self-cleaning film system inclu...
